Description

Technical Field

[0001] The utility model relates to the technical field of plastic processing, in particular to a plastic particle forming and extruding device. Background Technique

[0002] Plastic particles are raw materials for storing, transporting, and processing plastics in semi-finished form. These particles are composed of polymer materials. Substances such as ethylene, propylene, vinyl chloride, and styrene are prepared using raw materials such as petroleum, and through reactions under certain conditions, high molecular compounds are formed. During the production process, plastic particles usually need to be extruded and formed through an extruding device. This process includes heating and melting large pieces of plastic raw materials, extruding them into long strips through extrusion, and then cooling and cutting them at appropriate positions to form standard-sized particles.

[0003] After retrieval, a Chinese patent with the publication number CN213321582U discloses a plastic particle extruding device. The patent records that the first motor rotates, and through the transmission of the driving pulley, the driven pulley, and the belt, the conveyor belt is driven. Due to the setting of the rollers on the U-shaped bracket and the I-shaped rubber strip, the lower part of the conveyor belt becomes a horizontal conveyor, which is convenient for placing plastic raw materials on the horizontal section of the lower part of the conveyor belt and conveying them into the feeding hopper, and then entering the first extrusion barrel in the first casing through the feeding gap. After being heated and melted by the first heating tube group, the first motor drives the first screw to rotate through the first transmission shaft, so that the molten plastic in the first extrusion barrel is extruded into the connecting barrel. Auxiliary materials are added into the molten plastic in the connecting barrel from the feeding hopper, and after being mixed evenly under the action of the stirring shaft and the stirring blades, they enter the second extrusion barrel in the second casing. Adding auxiliary materials during the molten extrusion process of plastics saves time and improves efficiency. The second heating tube group continues to heat the molten plastic in the second extrusion barrel, so that the additives mixed in the molten plastic are dispersed and homogenized. At the same time, the second motor drives the second screw to rotate to extrude the molten plastic in the second extrusion barrel from the extrusion die head.

[0004] In this solution, the device directly drives through the belt and the belt pulley. When plastics are extruded and granulated, unnecessary resistance or speed mismatch will occur, resulting in uneven processing speed and reduced processing efficiency, thus affecting the production capacity and efficiency of the entire production line. At the same time, the product quality also decreases. To solve this technical problem, the utility model proposes a plastic particle forming and extruding device. Summary of the Invention

[0005] (1) Technical Problems to be Solved

[0006] In this solution, the device is directly driven by a belt and a pulley. However, during the process of plastic extrusion granulation, unnecessary resistance or speed mismatch may occur, which leads to uneven processing speed and decreased processing efficiency, thus affecting the production capacity and efficiency of the entire production line. At the same time, the product quality also deteriorates. To solve this technical problem, the present utility model proposes a plastic particle forming and extruding device.

At the same time, the rotating shaft is rotatably connected inside the housing. A rotating rod is rotatably connected in the middle of the housing. A middle gear is fixedly connected to the outer wall of the rotating rod, and the middle gear meshes with the small gear. The top of the workbench is fixedly connected with an outer cylinder. A screw rod is rotatably connected inside the outer cylinder. At the same time, an inner rod is fixedly connected inside the screw rod. The left end of the inner rod is fixedly connected with a large gear, and the large gear meshes with the middle gear. A feed pipe is arranged at the top of the screw rod.

[0014] (III) Beneficial Effects

[0015] The present utility model provides a plastic particle forming and extruding device, which has the following beneficial effects:

[0016] (1) By starting the motor at the bottom of the workbench, the small gear on the rotating shaft is driven to start rotating. The movement of the small gear rotates the middle gear with a diameter larger than its own, and this arrangement achieves a preliminary differential effect. The rotation of the middle gear further drives the rotation of the large gear with a diameter larger than its own, and at the same time drives the inner rod to start rotating, thus achieving the final differential effect. Such a design cleverly avoids the problems that traditional rotating shafts or belt drives are prone to breakage or detachment under excessive torque, significantly improving work efficiency and system reliability.

[0017] (2) By aligning the positioning block inside the connecting ring with the chute position at the right end of the inner rod and directly inserting it, at this time the blade on the connecting ring just contacts the outer wall of the baffle. Then insert the pin into the jack to achieve the fixing effect. The blade slides on the outer wall of the baffle to achieve the effect of quickly cutting into plastic particles. On the contrary, when disassembling, just pull out the pin directly, and the blade can be directly removed for replacement and repair, greatly improving work efficiency.

Detailed Embodiment

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0024] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0025] Embodiment 1: A plastic particle forming and extruding device, including a workbench 1. The outer wall of the left end of the workbench 1 is fixedly connected with a housing 4. The bottom of the workbench 1 is fixedly connected with a motor 2. At the same time, the output end of the motor 2 is fixedly connected with a rotating shaft 3. The other end of the rotating shaft 3 is externally fixedly connected with a small gear 5. At the same time, the rotating shaft 3 is rotatably connected inside the housing 4. The middle part of the housing 4 is rotatably connected with a rotating rod 6. The outer wall of the rotating rod 6 is fixedly connected with a middle gear 7, and the middle gear 7 meshes with the small gear 5. The top of the workbench 1 is fixedly connected with an outer cylinder 11. The inside of the outer cylinder 11 is rotatably connected with a screw rod 10. At the same time, an inner rod 8 is fixedly connected inside the screw rod 10. The left end of the inner rod 8 is fixedly connected with a large gear 9, and the large gear 9 meshes with the middle gear 7. A feed pipe 12 is arranged at the top of the screw rod 10. A pair of electric heating plates 22 are arranged inside the outer cylinder 11.

[0026] After pouring the raw materials into the inside of the outer cylinder 11 through the feed pipe 12, start the electric heating plates 22 inside the outer cylinder 11 to heat the plastic particles to make them soften. Then, start the motor 2 at the bottom of the workbench 1. It drives the small gear 5 on the rotating shaft 3. The rotation of the small gear 5 drives the middle gear 7 to rotate self - clockwise, and the speed gradually decreases. At the same time, the middle gear 7 also drives the large gear 9 meshing with it to rotate. The large gear 9 drives the inner rod 8 and the screw rod 10 to rotate inside the outer cylinder 11. Such a design effectively coordinates the rotation speeds of each component, ensures the stable rotation speed of the inner rod 8, and avoids the situation of excessive rotation.

[0027] Embodiment 2: The difference between this embodiment and Embodiment 1 is that, among them, the right - hand end inside of the outer cylinder 11 is fixedly connected with a baffle 13. A plurality of discharge holes are opened inside the baffle 13. A connecting ring 17 is arranged outside the right - hand end of the inner rod 8. A plurality of blades 19 are fixedly connected to the outer wall of the connecting ring 17, and the blades 19 are slidably connected to the outer wall of the baffle 13. A positioning block 18 is fixedly connected to the inner wall of the connecting ring 17. At the same time, a plurality of sliding grooves 15 are opened at the right - hand end of the inner rod 8, and the positioning block 18 corresponds to the sliding grooves 15. At the same time, the positioning block 18 is slidably connected inside the sliding grooves 15. A jack 16 is opened inside the right - hand end of the inner rod 8. A plug 20 is arranged on the outer wall of the inner rod 8, and the plug 20 is slidably connected inside the jack 16. A cooling tank 14 is arranged inside the right - hand end of the workbench 1, and a refrigerator 21 is arranged inside the cooling tank 14.

[0028] The plastic raw material is conveyed to the position of the baffle 13 and extruded and molded through the extrusion holes on the baffle 13. At the same time, the rotation of the inner rod 8 drives the connecting ring 17 to rotate. The connecting ring 17 drives the outer blade 19 to slide along the baffle 13, cutting the plastic into granules and making them fall into the cooling tank 14. Water is injected into the cooling tank 14, and the refrigerator 21 is started to cool the water, quickly solidifying the plastic particles into shape. This cooperation greatly improves the production efficiency. When the blade 19 is damaged, the pin 20 can be pulled out from the jack 16, and the connecting ring 17 can be directly pulled. The connecting ring 17 slides in the chute 15 through the positioning block 18, so as to quickly disassemble and replace the blade 19 for maintenance.

[0029] During operation, when the staff uses the device to extrude plastic particles, first pour the raw material into the inner part of the outer cylinder 11 through the feed pipe 12. At this time, start the electric heating plate 22 inside the outer cylinder 11. The plastic particles will be heated and softened by the electric heating plate 22. Then start the motor 2 at the bottom of the workbench 1. Under the action of the motor 2, the small gear 5 on the rotating shaft 3 is driven to rotate. When the small gear 5 rotates, it will drive the meshing middle gear 7 to rotate self - rotatably, and the speed will decrease. At the same time, the middle gear 7 will also drive the meshing connected large gear 9 to rotate. At this time, the large gear 9 will drive the inner rod 8 and the screw 10 to rotate inside the outer cylinder 11. Through their cooperation, the inner rod 8 will not rotate too fast when rotating, and start to convey the plastic raw material to the position of the baffle 13, and extrude and mold it through the extrusion holes on the baffle 13. When the inner rod 8 rotates, it will drive the connecting ring 17 to rotate. At the same time, the connecting ring 17 will drive the outer blade 19 to slide along the baffle 13, cut the plastic into granules, and drop them into the cooling tank 14. Add water to the cooling tank 14. By starting the refrigerator 21, the water will be refrigerated, so that the plastic particles will quickly solidify into shape. Through their cooperation, the working efficiency is greatly improved. When the blade 19 is damaged, by pulling out the pin 20 from the inside of the jack 16 and directly pulling the connecting ring 17 outwards, the connecting ring 17 slides in the chute 15 through the positioning block 18, so as to quickly disassemble, repair and replace the blade 19.
